A deadly strain of bird flu has been detected in Africa's most populous city, the Nigerian commercial capital Lagos, Information Minister Frank Nweke confirmed.
"The virus has so far been indentified in 12 states, including Lagos, as well as around the federal capital Abuja," Nweke told AFP.
The detection of the virus in Lagos will raise fears that Nigeria's outbreak H5N1 strain of bird flu, which has killed more than 90 people since it broke out in Asia in 2003, could be spreading out of control.
